Question 1: The user will enter a list of numbers and a separate number. The program will display the index at which the number is present in the list. If the number is absent, it'll return -1. Do NOT use built-in functions for searching.

a=(input("Enter the numbers :").split(","))
c=len(a)
b=int(input("Enter another number :"))
i=0
while (i<c):
    
    if (int(a[i])==b):
        print("List has an equal number at index ",i)
        break
    i=i+1
if(i==c):
    print("-1")
Enter the numbers :22,45,67,89 Enter another number :89 List has an equal number at index 3
